There are few shows as epic in scale as the Olympics opening ceremony - but if one dares to even try, it's the closing ceremony. And now, with the games beginning to wind down, speculation is turning to what the 2012 show will offer - and what fans really, really want to see.

According to the
Los Angeles Times, the reunited
Spice Girls will take the stage on Sunday for a massive show entitled "A Symphony of British Music." Also expected to play are legendary rock band
The Who, chart-topping songstress
Adele and theatrical rockers
Muse. British singer
Ed Sheeran is reportedly teaming with some combination of former
Pink Floyd members as well, perhaps promising something special for fans of the band that remain so popular after all these years.

Also on tap is
Ray Davies, who will likely continue to stop short of a full-on reunion of
The Kinks but perform "Waterloo Sunset" solo, according to
the Telegraph. Then, of course, are the boy bands:
Take That and
One Direction are rumored to also be on tap.

According to the
Herald Sun, additional names could include
Coldplay,Queen,
Madness,
Annie Lennox and
Kaiser Chiefs. Finally,
George Michael has confirmed that he will be reuniting
Wham! for a very special performance.

"Spending most of the next week rehearsing like crazy for the Olympic closing ceremony," he
tweets.

'To me, this should be the greatest after-party in the world," David Arnold, music director of the Olympic Closing Ceremony, tells the Telegraph. "If the Opening Ceremony was the wedding, then we're the wedding reception."

"We're the one where everyone gets out of their cars at the village hall, goes 'Wasn't that lovely, everyone looked great, let's put on Blame It On the Boogie and have a laugh," Arnold says of the intended difference in feeling between the opening and closing ceremonies.

"It needs to be something where everyone, including the athletes, is going to be able to let off steam. There are seven and a half thousand of them there, so it's a show for them all to get involved with, and hopefully it will wrap up the spirit of what these Games have been, which is slightly anarchic, slightly mischievous, funny, heart-warming, emotional, inspiring, and uniquely British."
